Patent

CA 2499275

The present invention relates to a process for treating a solid material containing at least one zeolite and being at least partly crystalline or treating a shaped body obtained from said solid material wherein said solid material or shaped body is brought in contact with a composition containing water after at least one of the following steps of an integrated process for producing a solid material or a shaped body containing at least one zeolite: (i) after step (II) of separating the at least partly crystalline solid material from its mother liquor or (ii) after step (S) of shaping said solid material into a shaped body or (iii) after a step (C) of calcining said solid material or said shaped body. The present invention furthermore relates to the solid material obtainable by the inventive process and the shaped body obtainable by the inventive process. The present invention also relates to the use of the solid material or the shaped body as mentioned above as a catalyst in chemical reactions, in particular in reactions of compounds containing at least one C-C double bond with at least one hydroperoxide.

La présente invention concerne un procédé de traitement d'une matière solide au moins partiellement cristalline et contenant au moins un zéolite, ou de traitement d'un corps moulé obtenu à partir de ladite matière solide. Cette matière solide ou ce corps moulé est placé(e) au contact d'une composition contenant de l'eau, après au moins la mise en oeuvre d'une des étapes suivantes d'un processus intégré de production d'une matière solide ou d'un corps moulé contenant au moins un zéolite: i) après l'étape II) de séparation de la (des) matière(s) solide(s) au moins partiellement cristalline(s) de sa (leur) solution-mère; ou ii) après l'étape S) de moulage de ladite matière solide en un corps moulé; ou iii) après une étape C) de calcination de ladite matière solide ou dudit corps moulé. L'invention concerne également la matière solide pouvant être obtenue par le procédé de l'invention et le corps moulé pouvant être obtenu par le procédé de l'invention. L'invention concerne en outre l'utilisation de ladite matière solide ou dudit corps moulé comme catalyseur dans des réactions chimiques, en particulier dans des réactions de composés comprenant au moins une double liaison carbone-carbone avec au moins un hydroperoxyde.
